Supplied in an amber bottle with eye dropper for convenience, FermCap S is a great way to control foam either during the boil or during fermentation. This means you're able to fit more wort in your kettle or fermenter for more finished beverage. When using FermCap you will have less blow-off from fermentation. Just add 1-2 drops per gallon in your kettle and have no worries about boiling over or add the same amount to your fermenter when you pitch your yeast!
FermCaps S does not affect the head on your finished beverage, but can actually increase head-forming compounds.
